How To Change The Bearings In Your Mountain Bikes Front Wheel | MTB Maintenance

[@zanducu]

Amazing, I've just changed my bearings after watching this video. Really helpful, my friends told me I need special press and stuff but it worked perfectly with the old bearing.

[@Oxidarius]

Just changed the bearings of easton x5 front hub. Very proud of myself 😊

[@maxb7281]

This how I have always done my bearings I do also like to pop my bearings in the freezer proir to fitting I find they go in a better.

[@oscarlangley7887]

Brilliant! Love tips like this. Will definitely be trying it out tomorrow!

[@redtobertshateshandles]

That creates condensation. Not something I want inside my bearing. It's OK in something that gets hot like an engine. Spray grease is the same.

[@ToThePointCT]

@@maxb7281 is that safe for the bearing? 😊

[@jeepsterc104]

I hope they could also show how the other major Hub brands were serviced.

[@CA66Y28]

Do a vid on dt Swiss hubs

[@mikeljhonson8959]

After carefully watching the tutorial i felt i should have done something as well. finally ordered a set of Vittoria tyres. Obviously skinwall.

[@leon_brave_racing898]

I didn't know he was at gmbn, that's cool to know.

[@alkaholic4848]

This video really confused me - I have a fairly modern mountain bike, with a quick release front wheel, but after spending hours trying to puzzle how to tap the axle out, i realised it's actually still using cup and cone! I didn't think they'd used cup and cone on quick-release axles, if I knew they existed I wouldn't have had such difficulty working it out. Might have been worth mentioning!

[@villimagg]

This is quality content. Please keep this up. Very necessary.

[@richlijacanacua]

Thank you for this awesome video tutotial!

[@TopC333]

How do you know what size bearings to order? On my KTM the year & model is all you need but where do you start on mtb? I don’t even know the make of the hub.

[@jamesdspaderf2883]

Very informative. I was hoping for information about sizing of bearings to know if this is standard or not.

[@-insertname-9784]

am i missing something? I have a Roval front wheel with specialized hi-lo hub.... but i cannot get the bearings out in any way at all. its causing me so much stress and no one on youtube is talking about how to do it...

[@DigiPal]

Don't know if you'e going to read this. Just want to know if I can convert loose bearings to cartridge ones. It's for a generic kind of wheel.

[@alkaholic4848]

Did you ever find the answer to this? All google/youtube finds me is replacing like for like, can't find any info on changing from one type to the other.

[@5492sparky]

Well explained Henry.

[@rupedog]

'Banger' vid H as ever... for home mech some other ideas that are maybe safer (less chance of damaging hub/new bearings from not going in square) is to make your own press with threaded rod nuts and washers (or sockets). And can use sockets to drift bearings in, but also to drift second one out square (socket on a extension piece).

[@jonathangoedefroot5902]

After how many time/km you should change your bearings?

[@THEGEEK2001]

Use rear of a socket instead of old bearing

[@Chelly5171]

Is the dtswiss m1900 different?

[@shitina.bucket9699]

Can I switch ball bears to the one you used?

[@alkaholic4848]

Did you ever find the answer to this? I'm guessing you mean replacing cup and cone bearings with sealed bearings. I've tried several search terms but it looks like i've gone beyond google's capability to understand, all its suggestions are like for like replacements.

[@myusernameislongerth]

how does one figure out which bearings to buy? is there a standard, or is it just "take it apart and see, and then wait till replacements arrive"?

[@AnotherMrLizard]

There is no standard, if you have branded hubs you can generally look up the diagrams and it’ll show the bearings size. Otherwise yes pull apart and read the codes off the seals or remove and measure yourself.

[@kakasensei6789]

Sir what size of bearing in front of tire of bike

[@James-dn1hu]

How do I get the end caps out there is not a Allen head like on yours

[@tychoMX]

James check mfr. manual. So many variations: hex wrench inside with threads, interference fit, one side with wrench flats and the other hex, both sides with wrench flats...

[@knott4me561]

90% simply pull off

[@joshuavezina1910]

If you can’t see slots for wrenches on the outside, odds are they just pull right off. (Can be very tough to pull off, depending on the wheel) If it’s a mavic wheel, you may need the mavic specific tool to unthread the end caps of the axle.

[@davidmatyja5485]

Hey guys, I have a 2017 Kona process 153 and need to change out the bearings in my front hub. Do the same steps apply to take out those bearings?

[@MCNIBBLE]

After the last 25 years I’ve never had to replace wheel bearings. Had a set of xt hubs on a hard tail for 18 years and was in thetford Forest most weekends.

[@mcnorm4023]

that's why thetford got nothing extreme cupla pot holes and roots

[@lwittrock1]

Great video

[@TheyForcedMyHandLE]

By using the axle to install the bearing, I'm pretty sure you essentially just hammered it in via the inner race, which is a no-no.

[@sullycliftona123]

How can i get security skewers off its driving me nuts on my dt swiss i cant get tgem off plus a washer makes it tight getting on and off forks ,i bought off e bay ..any suggestions ..i have no key to get them off ..plastic thing covering the bearings..anyone with thease skewers will know

[@david37Y]

I have a Bontrager Kovee Pro wheelset, and it’s very hard to make the bearings come out, how can I make it easier to replace them? Wd40? Read it’s similar to Dt Swiss hubs, similar process, but can’t figure it out, help!

[@gmbntech]

If they're 100% coming out, try using some penetrating solution to try and loosen them up. However that'll also do a number on any grease in and around the bearing so you'll have to make sure they're out out and you can clean the area before fresh grease and new bearings :)

[@david37Y]

GMBN Tech thanks guys! ;)

[@carbonsuicidemtb1583]

I'd be careful knocking a bearing in on the axle, the end cap will push against the centre ring of the bearing and potentially damage the balls and races, leading to an "indexed" or grumbling bearing with a much shorter life

[@DaveMustaine.]

If you can't get the bearings out easily, use an angle grinder! 👌

[@kristen7192]

No a blow torch and chisel work best

[@jltrack]

Dave Mustaine lol don’t do this. Use a proper bearing puller or take it to the bike shop as a last resort.

[@joshuavezina1910]

And then when that doesn’t work, don’t be surprised if the shop charges you triple to fix a seriously bodged hub. Had a guy come in to have square taper cranks removed a while back, easy job until he grinded the bolt to use a giant flathead to remove it.

[@powerbeast5691]

Lots of videos explaining how to replace, but I cant find a video that explains if/when it needs to be replaced. Mine doesnt rotate very well, if I spin it good it stops in 0.1 second. Is that normal?

[@david94549]

You pretty much just answered your own question, it needs to rotate well. There should be very little to no play between inner and outer race, if the bearing is loud and clunky when turning it's a no go, if it doesn't turn freely it's a no go

[@magnumllama400]

@@david94549 where do i get bearings from? And how do I learn the correct size?

[@rugtop880]

This seems like a video for anyone who wants to start running a bike repair shop not your average bike rider. But thx anyway

[@rupedog]

Easy to make your own press... should do a series on home made bike tools...though guessing park would not be a happy sponsor!🤔😬

[@knott4me561]

Whilst making kit at home to use on your bike is very rewarding as well as economical it's really difficult for a mainstream KZbin Chanel to dive fully into this .sadly all it would take is one person to replicate the tool damage a hub etc and there comes in the liability side of things . In my situation i look after an entire bike clubs mountain bikes so it's paid dividends for me to invest in the right tools for the job and and over the years this now enables me to service the club's bike not only efficiently but very cost effective . So for eg if yoh have just even a small group of friends you all need your frame pivots changing at some point you could buy the RRP bearing press and then individually but the appropriate adapters for each bearings between you and often some of the adapters will cross over as for eg 6901 is a common pivot bearing and it's a great way to all learn even if one members is more competent than the others .

[@joshuavezina1910]

Who even has a full park bearing press? Wheels MFG or Enduro all day, every day.

[@carbonsuicidemtb1583]

A short length of 10mm stud bar, nuts and washers from the local hardware store can save you the cost of a very expensive press tool

[@jbogert100]

Everything functions properly kzbin.infoUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Nothing was damaged in the box aside from a decal on the fork. The decal was missing a piece of a corner but I ended up peeling them off anyways. Assembly is easy BUT make sure you tune up the derailleurs. Both the front and rear need adjusting. I'd advise going to a bike shop but I opted out and put in 10+ hours with the help of KZbin. Ended up fraying a shifter cable but all in all I learned from the experience. The Brakes work well but the front caliper needs adjusting or at least mine did because the rotor was rubbing against the pads. Make sure you swap out the seat, grips, and pedals. For the short run you'll be fine though. I've read that this bike isn't built yet for hard trails but I just need it for the city. PA has some of the worst roads and being in a mountain this was a great choice. Worth the investment!

[@grindeyyyyy]

I can press in with my axle, the only issue for me is getting the cone nut off on 1 side

[@MrRobertNav]

Great Content as usual thanks! I noticed that my front wheel has a lot of "play" side to side when rolling on flat, I check and looks aligned (I followed your how to true a wheel videos), is there anything I should try to tight maybe? Is boost 27.5 " Thanks!!!

[@esurfer89]

Tighten this bearing hub. You might need two different size wrenches.

[@dirtjumpingfarmer]

Just use a long 16mm socket if you got one...

[@danquerelle7822]

#AskGMBNTech Hi, I am building a new bike and I am looking at a yeti SB5+ frame and it says it can have a150mm of travel up front (forks) but I am curious to know what would happen if I were to put a 160mm of travel up front. Would you recommend it or not. Thanks

[@garywinslow5607]

Frosty-_-Man raised bottom bracket, stack height increases, reach decreases. Higher BB usually makes cornering less stable as bike is higher, stack height and reach are rider specific. Also, do Yeti warrant the frame with 160mm? Personally, for 10mm I wouldn’t bother. Minimal gains.

[@danquerelle7822]

Gary Winslow ok thanks

[@gulusus884]

Hi guys I love your videos, can you please make the same on a rearwheel

[@joshuavezina1910]

gülüsüs every wheel will be different. Some will need to have to pawl ring removed to access the drive side bearing, while others are as easy as the front wheel. Depends what wheel you’re working with.

[@brandonreimer184]

A block of wood is a great substitute for a plastic ended hammer.

[@Ryann_1998]

Hi guys, I have a old bontrager big earl front hub and the bearing need replacing.. but it’s seems to be a fixed unit? There’s no end cap? Any information would be much appreciated, Cheers.

[@user9894]

Hey Gmbn Tech why do we need to change mtb spokes?

[@andrei3720]

If theyre bent

[@knott4me561]

Spokes over time can actually fatigue.so if your replacing the odd spoke on an aging wheelset and more spokes keep snapping it's time to get the wheel relaced

[@darcyphillips70]

Hmm, I have an issue with all the weight being placed on the spokes throughout removal and installation... no matter how gentle you are, this is still not ideal and this method also relies on the premise that the bearing comes out easily

[@knott4me561]

If the surface supporting the spokes in that area was solid I'd agree with you but given the soft ish nature of the roll of tape and the fact Henry placed it at the end where there is a lot of strength it really isn't an issue and if the bearings don't come out easily then you have a bigger issue that where the spokes are being supported. Hub Bearings really shouldn't be that tough to remove even if neglected given there generally at least a 6902 or above in size they will tap out with a minimal amount of effort .

[@joshuavezina1910]

Most wheel builders will actually tap the spokes going outward with a mallet when building the wheel to release slack that will potentially come out later. I wouldn’t worry about spreading that force out over 8-9 spokes when the guy who built the wheel probably hit them all individually.

[@jonathanzappala]

I just think this is too important to bodge. This would be one of the few jobs I’d go to the bike shop

[@joshuavezina1910]

Jonathan Zappala as a mechanic in a shop, I would agree. Most shops won’t charge you much, especially if you brought the wheel in with the bearings already punched out and just wanted new bearings punched in.

[@____________________________.x]

0:50 "if in doubt, look it up in your manual" - ...seriously? what manual? not everyone has a shiny new bike, many are second hand and may have been altered from stock, and as far as I can tell manufacturers give no flying pokes about archiving the original bike spec for you to even begin to research this. I've a box full of worn parts and I have absolutely no idea what they are, who even made them or where to start looking for replacements. Like bearings, what part am I looking for? or is there a generic bike front hub bearing that fits everything. These bike maintenance videos are great for showing you what's inside, but we don't have a magic parts fairy handing us a service kit with all the right bits, and that's a massive problem in trying to maintain a bike that's more than a month old. I can find more detailed repair information from the manufacturer of 40 year old IT equipment, than I can find just the brand name for the freehub of a 5 year old bike. I can't even get a paint code from them...

[@____________________________.x]

OK, the sealed cartridge bearing will have a code printed on the side (the plastic disc bit), just look this up. Someone in the UK recommended SimplyBearings in Lancashire

[@jbodden6977]

gee, everything but what I searched for...

[@05hino]

Hay guys is it normal for your rotors to discolor

[@joshuavezina1910]

Replace those bad boys lol

[@joshuavezina1910]

Discolouration is caused by heat transfer. Carefully inspect the rotors and make sure that they are not bent or losing material at the braking surface. It is perfectly normal for rotors to get discoloured, but only to a point. If they were starting to get very colourful, I would replace them. Dirt will not discolour a rotor.
